UNITED STATES PATENT OFFICE.

WILLIAM J'. MARTUS, OF WHITESBORO, NEW YORK, ASSIGNOR TO CHARLES A. POWELL, OF WHITESBORO, NEW YORK.

SEWING-MACHINE GUIDE.

To all whom it may concern Be it known that I, IVILLIAM J. Miin'ros, a citizen of the United States, residing at Whitesboro, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Sewing- Machine Guides, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to a sewing-machine guide, and I declare the following to be a full, clear, concise and exact description thereof, sufficient to enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings inwhich like reference characters refer tolike parts throughout the specification.

The object of the invention is to provide a covenient means whereby the edging guide of a sewing machine may be readily elevated to a position to present a surface against which the garment or article worked upon, may be disposed for guiding same. Said means also contemplates means for lowering said guide to a position flush with the upper surface of the sewing machine, whereby said guide will be in inoperative position.

Other objects will appear from the drawings in which Figure 1 is aside elevation of a sewing machine to which the means for elevating and lowering the guide has been attached;

Fig. 2 is a perspective view of the means for elevating and lowering the guide, shown detached from the machine; Fig. 3 is a fragmentary plan view; Fig. 4 is a detail somewhat enlarged of said means in side elevation; Fig. 5 is a fragmentary detail view, somewhat enlarged showing the edgling guide in raised position; Fig. 6 is a fragmentary plan view of a modified means for elevating and lowering the edging guide Fig. 7 is a detail somewhat enlarged of the modified means detached.

Referring more particularly to the drawings, the base of the sewing machine is represented by 1 adapted to support goose neck 2 having means to support presser bar 3 holding presser foot 4: and also having means to support needle bar 5 holding needle 6. Said needle bar 5 and needle 6 are vertically reciprocated by needle-bar I Specification of Letters Patent.

rocker arm 7 pivotally mounted at 8 to goose neck 2. Said needle-bar rocker arm 7 is rocked by its connection with pitman rod 9 which is reciprocated by its eccentric mounting upon spindle 1O revolved by drive wheel 11. The lower end of needle-bar rocker arm 7 is pivotally connected as at 12 to plunger 13 carrying under needle or shuttle 14. The aforesaid parts are well known in the art and I do not deem it necessary to enlarge upon their description.

The improvement resides in the means for elevating and lowering the edging guide which I shall represent by 15. Said guide is mounted in the machine by a spindle 27 slidingly mountedin recess 16 bored into base 1, and is disposed therein whereby one of its surfaces will reciprocate adjacent presser foot 4:. In order to elevate said guide to the position shown in Fig. 5, I employ a cam 17 integral or otherwise secured to bell crank arm 18 pivoted to the upper surface of the sewing machine as at 19. Said bell crank arm 18 may be operated by handles 20 or 21 projecting through slots 22 and 23 respectively, provided therefor in said frame. Obviously, the rotating of bell crank arm 18 in one direction will cause cam 17 to ride under the lower surface of the head of edging guide 15 and elevate same to the position shown in Fig. 5. The edging guide 15 will remain in this elevated position because of the level surface at the top of the incline of cam 17. There is also provided upon cam 17 a shoulder 24 against which the side surface of guide 15 may abut to form a positive stop. When arm 18 is swung in the reverse direction, guide 15 will be lowered to a position flush with the upper surface of the sewing machine.

In Figs. 6 and 7 I have shown a modification of the means for elevating and lowering the guide 15. Said means embodies an inclined plane 25 slidingly mounted in recess 26 provided in spindle 27 of edging guide 15. Said plane 25 is actuated to and fro by lever 28 pivotally mounted to the upper surface of the sewing machine as at 29 and is also pivotally connected to extended portion 30 of plane 25. Incline plane 25 is provided with a straight edge 31 to adapt said plane 25 to remain at any position within the limits of its movement.

Plane 25 has a horizontal surface at 82, adapted to hold guide 15 thereon, when in that location. A shoulder is represented by 33 whereby plane25 is prevented from moving beyond recess 26 in plane'25. 7

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: v

l. A guide for a sewing machine consisting of a spindle mounted in the work-plate of themachine to be raised and lowered, the spindle having at its upper end a guide member, the face of the work-plate being cut out to receive said guide member when lowered, a bell-crank lever pivotally mounted at the rear part of the work-plate and having an arm extending to and projecting from the front of the machine and a second arm projecting from the point of mounting of the lever partway forward across the work-plate and thence laterally and having a cam-shaped end, the said end lying beneaththeunder surface of the guide member whereby the swinging of the lever operates to press thecam-end under the said guide Copies of this patent may be obtained for fivellcents h, by addressing the Commissioner of Patents, Washington, I).

member at the top of the spindle an hold .the same in raised position.

toward the operator, a cam-armmounted on said lever, the cam acting on the under-surface of the guide to raise the same, the cam being also provided with a level surface at its higher end for-the fixed support of the guide, and a stop at the end of said level part, substantially as described.

In testimony whereof I have hereunto affixed my signature in the presence of two witnesses. 7
